Thank you for the explanation.
Since I'm writing a module, I didn't think a one-liner was sufficient
proof that state variables are reliable. Sorry I didn't make that
clear. I was worried about edge cases, and also wondered if there may
be a better way to implement my proposal--I don't know Perl 6 and Rakudo
well enough. It seems like state variables are best, right now.
Thanks!
Ted
